Oracle Cloud Infrastructure 2022 Developer Professional Sample Questions (Q74-Q79):

NEW QUESTION # 74
Which testing approaches is a must for achieving high velocity of deployments and release of cloud-native applications?

  • A. Automated testing
  • B. A/B testing
  • C. Integration testing
  • D. Penetration testing

Answer: A Explanation:
Oracle Cloud Infrastructure provides a number of DevOps tools and plug-ins for working with Oracle Cloud Infrastructure services. These can simplify provisioning and managing infrastructure or enable automated testing and continuous delivery.
A/B Testing
While A/B testing can be combined with either canary or blue-green deployments, it is a very different thing. A/B testing really targets testing the usage behavior of a service or feature and is typically used to validate a hypothesis or to measure two versions of a service or feature and how they stack up against each other in terms of performance, discoverability and usability. A/B testing often leverages feature flags (feature toggles), which allow you to dynamically turn features on and off.
Integration Testing
Integration tests are also known as end-to-end (e2e) tests. These are long-running tests that exercise the system in the way it is intended to be used in production. These are the most valuable tests in demonstrating reliability and thus increasing confidence.
Penetration Testing
Oracle regularly performs penetration and vulnerability testing and security assessments against the Oracle cloud infrastructure, platforms, and applications. These tests are intended to validate and improve the overall security of Oracle Cloud Services.

NEW QUESTION # 75
You are tasked with developing an application that requires the use of Oracle Cloud Infrastructure (OCI) APIs to POST messages to a stream in the OCI Streaming service.
Which statement is incorrect?

  • A. The request does not require an Authorization header.
  • B. The request must include an authorization signing string including (but not limited to) x-content-sha256, content-type, and content-length headers.
  • C. The Content-Type header must be Set to application/j son
  • D. An HTTP 401 will be returned if the client's clock is skewed more than 5 minutes from the server's.

Answer: A Explanation:
Authorization Header
The Oracle Cloud Infrastructure signature uses the "Signature" Authentication scheme (with an Authorization header), and not the Signature HTTP header.
Required Credentials and OCIDs
You need an API signing key in the correct format. See Required Keys and OCIDs.
You also need the OCIDs for your tenancy and user. See Where to Get the Tenancy's OCID and User's OCID.
Summary of Signing Steps
In general, these are the steps required to sign a request:
Form the HTTPS request (SSL protocol TLS 1.2 is required).
Create the signing string, which is based on parts of the request.
Create the signature from the signing string, using your private key and the RSA-SHA256 algorithm.
Add the resulting signature and other required information to the Authorization header in the request.

  • A. 50 GB
  • B. 1 TB
  • C. 10 GB
  • D. 1 GB

NEW QUESTION # 77
You want to push a new image in the Oracle Cloud Infrastructure (OCI) Registry. Which two actions do you need to perform?

  • A. Generate an API signing key to complete the authentication via Docker CLI.
  • B. Assign an OCI defined tag via OCI CLI to the image.
  • C. Generate an OCI tag namespace in your repository.
  • D. Assign a tag via Docker CLI to the image.
  • E. Generate an auth token to complete the authentication via Docker CLI.

Answer: D,E Explanation:
Pushing Images Using the Docker CLI:
You use the Docker CLI to push images to Oracle Cloud Infrastructure Registry.
To push an image, you first use the docker tag command to create a copy of the local source image as a new image (the new image is actually just a reference to the existing source image). As a name for the new image, you specify the fully qualified path to the target location in Oracle Cloud Registry where you want to push the image, optionally including the name of a repository.
For example, assume you have a local image named acme-web-app:latest. Let's say you want to push this image to Oracle Cloud Infrastructure Registry with a name of acme-web-app:version2.0.test into a repository called project01 in the Ashburn region of the acme-dev tenancy. When you use the docker tag command, you'd name the new image with the fully qualified path to its destination, in the format <region-key>.ocir.io/<tenancy-namespace>/<repo-name>/<image-name>:<tag>. So in this case, you'd name the new image iad.ocir.io/ansh81vru1zp/project01/acme-web-app:version2.0.test. Subsequently, when you use the docker push command, the image's name ensures it is pushed to the correct destination.
To push images to Oracle Cloud Infrastructure Registry using the Docker CLI:
If you already have an auth token, go to the next step. Otherwise:

On the Auth Tokens page, click Generate Token.
Enter a friendly description for the auth token. Avoid entering confidential information.
Click Generate Token. The new auth token is displayed.
Copy the auth token immediately to a secure location from where you can retrieve it later, because you won't see the auth token again in the Console.
Close the Generate Token dialog.
